Power system stability in the transition to a low carbon grid: A techno‐economic perspective on challenges and opportunities

Abstract: Increasing power system stability challenges are being witnessed worldwide, while transitioning toward low‐carbon grids with a high‐share of power electronic converter (PEC)‐interfaced renewable energy sources (RESs) and distributed energy resources (DERs). Concurrently, new technologies and operational strategies are being implemented or proposed to tackle these challenges. Since electricity grids are deregulated in many jurisdictions, such technologies need to be integrated within a market framework, which i… Show more

“…In this context, the Department of the Environment, Climate, and Communications of Republic of Ireland (ROI) set a 70% renewable electricity target for 2030, with electricity projected to account for ≈ 30% of final energy use in Ireland [2]. One of the challenges of accommodating large shares of renewables in electricity networks is associated with frequency and voltage related stability challenges [3]. One particular aspect relates to the displacement of synchronous generators by converter-interfaced variable renewables technologies, which leads to a reduction in stored rotational energy (inertia), and faster power system dynamics, such that higher rates of change of frequency (RoCoF), lower frequency nadirs, and a higher likelihood of underfrequency load shedding can be expected, particularly in smaller, or (synchronously) isolated power systems, following a significant disturbance [3,4].…”

It follows that when a generator trips faster acting frequency responses are required in order to stabilise the system.…”

“…A GFM can control directly its voltage amplitude, frequency, and phase without relying on the strength of the grid. It can provide services such as (but not limited to) black start capability, virtual inertia, primary frequency support, and islanded operation capability [59].…”
